' 1 AUTOMOBILE WHEEL?" allwsubjects of the King nema B rit- Rain, and residents-of Cap v de la Madeleine,

in theProvince of Quebec and Dominion of Canada, have invented certa n new and useful Improvements in Automobile .13.? heels, of V which the followingis a trill; clear, and exact description. This invention relates to pneumatic cushioned wheelsanditheobject of the invention is to provide a more resilient wheel.

A second object'is to provide awheel in which the pneumatic tire'isprotected from punctures, blow outs and the like, by being kept clear of contact with the road and from p e pneumatic tire 12.- "The outer rim 13 is:

' the elements of the weather.

A further object is to eliminate skiddlng by providing theback wheels with solid 'tires' are used only on the front wheels to facilitate steering.

In our invention'we provide an automobile wheel where the pneumatic tire is pro- I tected by being enclosed inan all m'etalcas ing. This casing is provided byibuilding a hub, anouter rim on which is, mounted the outer solid tire. and two 'encasing plates or cover plates. The pneumatictire or pneu matic cushion 1s thus protected from 1n ury due to exposure or from coming in contact with sharp objects in the'path of the wheel. We also provide the wheel with a t1re with fiat tread for back wheels and a tire with round tread for the front wheels, thefforlner construction to prevent skidding and the like, and the latter for facilitatingthe steer- 9 'ing..' The cover plates are fixed to the hub and the outer rim is driven through the medium of a roller mounted; on-a hardened steel pin screwed into the rim of the wheel,

I the roller working within a slot cut in the cover plates. This slot allows the pinto take up anv variation in its position due to deflation of the pneumatic tire. I The rim is allowed to slide in the cover plates and the pins and rollers are the medium for driving the outer rim We also provide well lubricated brass wearing rings to eliminate the friction due to the cushionlng between the hub and the outer rim'.

A driving element' -is proo vided' between the hub and the outerkrim through the medium of the cover plates 15. Slots 17 are cut in the coverjplates 15 the sides of which engage "rollers 19. -The pins 2-0 screwed into the rim 13, support the rollers 19. The slot 17 allows therolle rs to acj i commodate themselves to'any position re quired caused through the deflation or ex pansion of the tire '12. The rollers 19 and i the; pins'QO are used as driving mediumor torque transmitter betweenthe hub andrnn. v

Toprevent undue wear and also to elimin-ate friction between cover plates 15 and the rim 13'we oro'vid'e' friction rin s 21 v h countersunk into the'rim 13. Theseplates are provided with holes22 which are filled with a good lubricant composition to elimi- I y nate friction between the rubbing, surfaces. Toprevent leakage of the lubr1cant,pack- 1ng' r1ngs23 are provided, arecess being provided in the rim for sai-dpackingI Soa'pstone 24,is placed around the tire 12, and

between it and the parts of the wheel coming in contact with it to reduce friction and wear of said tire 12. To inflate the tire the valve 25 is provided. In the drawing, Figure -2 shows a back or driving wheel which is bored and keywayed to suit the driving axle and it will be noted it is fitted with a fiat solid tire to prevent skidding. The front wheel can be fitted With a solid rubber tire of semicircular section and its hub can be bored to accommodate ball or roller bearings as required. The torque transmitter or driving element can be fitted to back wheels or driving wheels only. The rim 13 comprises an inner casting and two circular pressed rings bolted to said casting.- The outer edges oi the mm are formed to clamp solid rubber ti-re 14 as shown in accompanying drawing.

Having thus described our im entiolnwhat we clann 1s 1. A wheel structure comprising a hub, a

tire carrying rim surrounding the hub, a resilient cushion interposed between the hub and said rim, side plates secured to the hub and extending upon opposite sides of the rimgpins carried by the rim disposed for radial movement in elongated slots formed tion betweenthese parts.

In witness whereof, we have hereunto setin the said plates and rollers carried by the pins for engaging the walls of the slots.

2. A wheel structure as recited in claim 1 in which the roller carrying pins arethreaded into the rim so as to be removable therefrom. s

3. A wheel structure as recited in claim 1 including friction rings secured to opposite sides of the rim by means of said pins and rollers, and adapted for engagement with said plates.

A pneumatic tire comprising a hub, side plates secured to the hub and projecting be yond the periphery of the same, a tire carrying rim fitting between said plates, means establishing a '(lllVG connection between the hub and rim, a pneumatic tube interposed between the rim and hub and a filling of soapstone interposed between the said tube and the side plates to reduce-wear and fricour hands.
